Time Out says
If you’re a less committed camper, stop by this Shinjuku dealer for a quick rental. They allow you to bring the gear back straight after use, without worrying about cleaning or carrying it all the way back to Tokyo – use the COD slip provided to drop your item off for return shipping at the nearest convenience store. Two days with a seven-piece hiking set, which includes rainwear, trekking poles, a backpack and shoes, can be had for ¥13,000, while more expensive packages also come with helmets. Individual pieces of clothing are also available, so music festival-goers can easily pick up an extra layer of wear in advance just to be on the safe side. See their English-language website for a full list of items and reservations.
